The reason why Liverpool didn't get a penalty after Yehor Yarmolyuk was shown a red card for violent conduct in the Brentford box has been confirmed.

Tensions boiled over during Liverpool's tough away day against an in-form Brentford side after Yarmolyuk was sent off for headbutting Jeremy Jacquey in the box.

Despite the referee agreeing that Yarmolyuk had committed violent conduct in the box, a penalty was not awarded, and now we know why.

Why Liverpool weren't awarded a penalty for Yehor Yarmolyuk headbutt

After a dramatic first half led to several Liverpool players coming off injured, fans were concerned when they saw Jacquet writhing on the floor just moments before a corner kick was taken.

Shortly after, it was revealed that Jacquet's pain was caused by Yarmolyuk, who appeared to headbutt the Liverpool defender out of frustration while trying to defend the upcoming corner.

After a VAR review, referee John Brooks agreed that the Ukrainian had committed violent conduct and immediately sent him off with a red card.

But, because the ball wasn't actually in play as Liverpool prepared to take a corner, the Reds were not awarded a penalty.

IFAB Law 12, which applies in the Premier League. It states: “Direct and indirect free kicks and penalty kicks can only be awarded for offences committed when the ball is in play.”
